Detailed explanation of installing php source code under linux

There are several steps to install the php source code:

1. Move the downloaded binary package to the /usr/local directory and unzip the file package

tar zxvf php-7.1.4.tar.gz

2. Enter the decompressed php folder /usr/local/php-7.1.4, install the dependencies, compile and install

yum install  libxml2  libxml2-devel

./configure --prefix=/usr/local/php  --with-zlib --enable-zip --with-openssl --enable-fpm --enable-mbstring 
--with-libdir=lib64 --without-pear  --disable-phar

make

make test

make install

3, php configuration

#php的配置文件为 php.ini
cp /usr/local/php-7.1.4/php.ini-production   /usr/local/php/lib/php.ini

#使得另一种方法来管理服务：
cp /usr/local/php-7.1.4/sapi/fpm/php-fpm /etc/init.d/php-fpm

#添加执行权限
chmod +x /etc/init.d/php-fpm

#php-fpm的配置文件
cp /usr/local/php/etc/php-fpm.conf.default   /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default   /usr/local/php/etc/php-fpm.d/www.conf

Modify the maximum limit on the number of php-fpm processes according to the machine configuration, which is limited to /usr/local/php In /etc/php-fpm.d/www.conf

Usenetstat -napo |grep "php-fpm" | wc -l Check the current number of fastcgi processes, if If the number is close to the upper limit configured in conf, you need to increase the number of processes.

But you can’t increase it endlessly. You can adjust the number of php-fpm sub-processes to 100 or more according to the server memory. On a server with 4G memory, 200 is enough.

pm.max_children = 200
pm.start_servers = 10
pm.min_spare_servers = 8
pm.max_spare_servers = 12

4. Set environment variables

vi /etc/profile

After opening, add the following configuration at the bottom of the document:

export PATH=/usr/local/php/bin:$PATH

:wq! Save and exit, execute Run the following command to make the changes take effect

source /etc/profile

5. Start the php test

#启动
/etc/init.d/php-fpm

#测试php
cd /usr/local/nginx/html
vi test.php

Add the following content:

<?php  
 echo phpinfo();  
?>

:wq!Save and exit.

Browser input: http://10.62.32.123/test.php

If it appears: PHP Version 7.1.4 interface, display the detailed configuration interface of php , indicating that the installation is correct.

6. Restart and stop php

php 7.1.4 php-fpm is already embedded in the source code, you only need to configure it when Just add compilation parameters.

However, php-fpm under php 7.1.4 no longer supports commands such as /usr/local/php/sbin/php-fpm (start|stop|reload) that php-fpm previously had. You need to use Signal control:

The master process can understand the following signals:

SIGINT, SIGTERM Terminate immediately

SIGQUIT Smooth termination

SIGUSR1 Reopen the log file

SIGUSR2 Smoothly reload all worker processes and reload configuration and binary modules

Example:

php-fpm Close:

kill -SIGINT `cat /usr/local/php/var/run/php-fpm.pid`

php-fpm Restart:

kill -SIGUSR2 `cat /usr/local/php/var/run/php-fpm.pid`

View the number of php-fpm processes:

ps aux | grep -c php-fpm
netstat -anpo | grep "php-cgi" | wc -l
netstat -anop | grep "php-fpm" | wc -l
